Yes there both USB and if you meen do they both work in noral mode ( yes )
And if I change the bios they will not work in PS2 corecct ?
The only setting to change in BIOS is the one to enable USB Legacy Support so the power to your USB ports is switched on early enough for Safe Mode to be able to use them. Otherwise, as Graywolf says, you need to use the PS2 sockets and they always work as soon as the power switch is turned on.
